Tlou Energy, the AIM and ASX listed company focused on delivering power in Botswana and southern Africa through the development of coal bed methane (‘CBM’), has commenced work on the planned 250KM 2D seismic program across its 100% owned Lesedi CBM Project and the adjacent Mamba Permit.  


  • 250 km 2D seismic program will target areas considered to be highly prospective for the addition of Gas Reserves
  • Aim to increase Gas Reserves at both the Lesedi and Mamba projects
  • Results will facilitate location of vertical drill holes to further confirm Gas volumes in the ground
  • Positive results will further de-risk the Lesedi project

Tlou’s Managing Director Tony Gilby said:

‘Tlou is extremely pleased to have the Seismic program running and to be working with Velseis, who are highly experienced in this area.  This survey will give us the opportunity to expand our Gas Reserves and Resources as we progress towards developing the first CBM gas to power project in Botswana.

The seismic survey will assist in the next step of our plan to drill more wells by providing us with enhanced knowledge of the sub-surface in our project areas.  Results from subsequent core well analysis may also lead to further Gas Reserve and Resources and consequently add further value to Tlou.

We look forward to updating the market as the seismic program progresses.’


Seismic Survey

The seismic survey will stretch across 250km of the Company’s Lesedi and Mamba projects including over part of the Mining Licence area.

The Company have identified potential gas reservoir compartments outside the currently mapped Gas Reserve areas.  These compartments have relatively sparse geological control other than the existing aeromagnetic data so new seismic data could demonstrate that continuity of gassy coal exists and this could lead to expanded Gas Reserves and/or Resources.

The seismic lines have been inspected and cleared and equipment and safety checks have been completed in advance of the commencement of the acquisition of the 2D data.  The acquisition involves specially designed tractors that are fitted with a vibrating plate, which transmits a frequency into the ground at specified locations. The reverberating frequency is recorded via highly sensitive geophones place along the seismic line, and this is interoperated by specialized software to identify the underlying structure of the formation.

Following this, the equipment is demobilized from site, seismic lines rehabilitated and an acquisition report is prepared, followed by interpretation of the data and an interpretation report. Thereafter the data is integrated with the existing aeromagnetic data to provide a clearer picture of the sub-surface geology.  The data will then be used to identify the initial areas for the drilling of Core wells and project development and used to assist in the expansion of Gas reserves and Contingent Resources.
